Video Chat with Unity3D and AR Foundation — Part 3: Remote Assistant App

This tutorial demonstrates how to create a remote assistant application using Unity3D and AR Foundation, with Agora's Video SDK for video streaming. The app allows users to share augmented reality (AR) objects from the sender's AR camera while excluding HUD UIs during screen sharing. The project consists of three scenes: Main, AudPlay, and CastAR. It uses multiple cameras to capture AR camera images and AR objects separately, then shares them with a remote audience client. The app also supports drawing on the shared AR screen by capturing touch points from the audience's device and rendering corresponding dots in the sender's 3D world.
